Usage

Here is a possible program to test your function:


package main

import (
    "fmt"
    "piscine"
)

func main() {
    fmt.Println(piscine.Unzipstring("6H8a"))
    fmt.Println(piscine.Unzipstring("3p6i1W"))
    fmt.Println(piscine.Unzipstring("2O5u2H0e"))
    fmt.Println(piscine.Unzipstring("2f"))
    fmt.Println(piscine.Unzipstring("2a 6p8f"))
    fmt.Println(piscine.Unzipstring("2p4;7g"))
    fmt.Println(piscine.Unzipstring("2t4dD"))
    fmt.Println(piscine.Unzipstring("82t4D"))

}
